Ability to transform his body into a variety of monstrous forms with unique abilities (such as a dragon form capable of flight and fire breathing). While in these forms he has enhanced strength, speed, stamina, and resistance to injury along with the special characteristics of each form. He was also shown to take on humanoid forms, specifically an armored form akin to Colossus and a mythological Nordic Troll. In all of these forms Freakshow was still capable of human speech.

Freakshow was one of the few survivors of the island of Genosha after the Sentinel attacks on the capital of Hammer Bay. Somehow he finds himself to be the traveling companion of Wicked and becomes an unofficial pupil of Professor X. He soon proved his usefulness in dispatching a skirmish between the Professor and the local bully, Unus the Untouchable. Knowing that he couldn't do anything to harm Unus, Xavier had Freakshow swallow the man whole. Because of Unus' natural force field he was unharmed, albeit shaken, when Freakshow vomited him up later.
During their efforts to rebuild Genosha, Freakshow took on a worm-like form and digested the debris of the shattered buildings to turn it into arable land.
Since the events of the House of M and the conclusion in Decimation, Freakshow was seen with a number of Genoshan mutants including Unus the Untouchable and Wicked where they were exposed to the Terrigen Mists which Quicksilver stole from the Inhumans to try to redeem himself and grant the world's mutants their powers back. However, the Mists have been shown to have adverse side effects.
